docs(wiki): reflect TLSF Phase 1+2 completion, Windows memory bugs, ZUI dock fixes, swapchain sync fix
Memory-Management.md:
- TLSFSlab section rewritten from 'planned, not in codebase' to shipped
Phase 1 (upload slabs, closure slab) + Phase 2 (typed Array/UnorderedHashMap
allocator, AssetManagerSlab); Phase 3 marked blocked with reason
- ArenaAllocator: documented move semantics, deleted copy ctor, AllocateNoZero,
alignment precondition assert
- New Windows Platform Notes subsection: the two real bugs found and fixed
(CreateSubArena eager commit; m_mem_page_size 32-bit truncation on LLP64)
with the actual mechanism and the general lesson
- PoolAllocator double-free/exhaustion rows updated from 'not detected' to
'fixed' (#697, #681)
- Thread safety table, performance table, container-ownership section all
updated to match shipped state instead of roadmap language
Containers.md: documented the TLSFSlab-backed init() overload for Array/
UnorderedHashMap as the fix for arena-abandonment on reserve/rehash.
Rendering-Domain.md: added a gotcha note on the viewport resize swap-and-reuse
section documenting the swapchain timeline backward-clamp bug (#736) and its
two-part fix (#738, #739).
ZUI-System.md: added a gotcha note on the docking section documenting the
two-round negative-rect scissor overflow bug (#732) and its fix (#733, #737).
Roadmap.md: new 'Memory and rendering hardening' section under the in-progress
Stable Core milestone listing all of the above with PR links; noted ZUI's
PR #679 merge; clarified the Future table's UI system row now that the
editor's own UI has shipped.
